The purpose of this study was to determine the effects of instruction and scaling up a control parameter (velocity of throw) on changes in throwing pattern. Sixty adult female throwers (ages 20-26 years) were randomly placed into one of four practice conditions: (a) scale up on velocity with no instruction, (b) maintain constant velocity with no…

The purpose of the present investigation was to compare the content of 8 weeks of training in young endurance-trained male and female runners and study the potential impact of this training content on performance. Fourteen men and 11 women performed two criterion exercises until exhaustion on an outdoor track before and after the 8-week training…

Early intervention approaches for facilitating motor development in infants and children with Down syndrome have traditionally emphasised the acquisition of motor milestones. As increasing evidence suggests that motor milestones have limited predictive power for long-term motor outcomes, researchers have shifted their focus to understanding the…

We present a project for a differential equations class: an analysis of an H. G. Wells story in which is given a submersible's descent time, its ascent time, and its eruption from the surface before splashdown. (Contains 5 figures.)

Several studies have shown the difficulties students encounter in making sense of situations involving rate of change. This study concerns how students discover errors and refine their knowledge when working with rate of change. The part of the study reported here concerns the responses of four precalculus students to a task which asked them to…

A self-paced program designed to integrate the use of computers and physics courseware into the regular classroom environment is offered for physics high school teachers in this module on projectile and circular motion. A diversity of instructional strategies including lectures, demonstrations, videotapes, computer simulations, laboratories, and…

This book is written for physical educators and others interested in the performance of the human body in motion. It is divided into four major catagories: (1) The discipline of human movement and its applications; (2) human beings and function through movement; (3) human movement; applied; and (4) human movement: generative and integrated. Six…

This is part of a series of 42 Calculus Based Physics (CBP) modules totaling about 1,000 pages. The modules include study guides, practice tests, and mastery tests for a full-year individualized course in calculus-based physics based on the Personalized System of Instruction (PSI). The units are not intended to be used without outside materials;…

This minicourse was prepared for use with secondary physics students in the Dallas Independent School District and is one option in a physics program which provides for the selection of topics on the basis of student career needs and interests. This minicourse was aimed at providing the student with an understanding of the physics of falling…

This book offers a perspective on creative drama, an art form akin to the spontaneous, imaginative painting produced by children, which frees the soul of the child to act naturally, give out unabashedly, and develop through such acting the realization of his own deep emotions. Critical of formal drama which can inhibit and deaden the free…

The papers presented in this book deal with the general area of motor skill acquisition and development. In section one, the first paper presents an overview of what has come to be known as "man as an information-processing system." Attention is focused on the transformation that the sensory input undergoes during central nervous system…

Various research studies concerned with the feedback from proprioceptors which accompany movement and the way in which this information is relevant to the control of activity are brought together in this volume. It is intended for the use of those who have some basic knowledge of human anatomy and physiology as well as an acquaintance with…

Provides an overview of the programing language PROLOG and highlights its educational uses. Explains how PROLOG serves as a model of representing commonsense understandings of motion. Identifies problem areas and proposes future tasks with the program. (ML)

Introduces a photogate arrangement using a photo-reflective sensor for air track experiments. Reports that the sensitivity to sunlight can be eliminated and a mechanically more convenient package produced. Shows the mounting, circuit, and usage of the photogate. (YP)

Examines preconceptions regarding several implicit vector characteristics that 15- to 17-year-old students possess just before taking their first physics course. Shows seven vector characteristics and three tasks for interviewing students. Presents the most common student preconceptions regarding each of the implicit vector characteristics. (YP)
